Answer: The answer is the first choice.
Explanation:
Because you must find the sin of the x values in the table.
Sin(7pi/6) = -1/2
Sin(5pi/4) = -sqrt 2/2
Sin(4pi/3) = -sqrt 3/2
Answer:
A
Step-by-step explanation:
Note that
x² + 12x + 36 is a perfect square → (x + 6)², hence
= = (x + 6)
Hence
f(x) × g(x)
= (x + 6)(x³ - 11)
= - 11x + 6x³ - 66
= + 6x³ - 11x - 66 → A
Answer:
a=3√77=26.3 ( rounded to the nearest tenth)
Step-by-step explanation:
hyp.=37
base=26
a²+b²=c²
a²=c²-b²
a²=37²-26²
a²= 693
a=√693
a=3√77=26.3 ( rounded to the nearest tenth)
Answer:
125 books
Step-by-step explanation:
225 multiplied by 5/9 is 125. That is how many books are mystery because 5/9 of 225 is 125.
Answer:
m∠CBD=68°
Step-by-step explanation:
BA is perpendicular to BD, meaning they form a right angle (90°)
This means m∠CBD + m∠ABC=90, or they are supplementary.
We have expressions given for these angles, so
4x+52+8x-10=90
12x+42=90
12x=48
x=4
Knowing x=4, we can substitute back into our expression for m∠CBD because that's what we're looking for.
4(4)+52=68
m∠CBD is 68°.
